hfsplus: don't use BUG_ON() in hfsplus_create_attributes_file()

hfsplus: don't use BUG_ON() in hfsplus_create_attributes_file()

When the volume header contains erroneous values that do not reflect
the actual state of the filesystem, hfsplus_fill_super() assumes that
the attributes file is not yet created, which later results in hitting
BUG_ON() when hfsplus_create_attributes_file() is called. Replace this
BUG_ON() with -EIO error with a message to suggest running fsck tool.
